The technology that makes the human body heat into electrical energy changes with technology called thermocouples. Is it? Thermocouples are shaped pair of thermoelectric materials that are so small and flexible. These thermocouples serves to capture the heat of the human body. Thermocouples are then printed and attached to your shirt or pants pockets.
Professor of electronic systems at the University of Southampton is named Stephen Beeby stated that "One side of the bag to the other side of the cold and heat. When your body produces heat through the bag, you are creating voltages and currents. Voltage and current simultaneously generate electromotive force . "
Then, the electricity created by the temperature difference between the inner and outer layers of the bag that is then used as an energy battery chargers your phone. So, the system works is like this if your phone is placed for 4 hours in a shirt pocket which has thermocouples, automatically your phone's battery charged for usage by itself for about 4 hours anyway.
This device has been available in the Isle of Wight Festival 13-16 June 2013 start in the UK, and will be present also in the other festival sponsor Vodafone.
Technological innovation around the mobile phone battery charging via body heat is already been done before by a graduate student from Wake Forest University, in North Carolina, United States in late February 2012. He named the technology as Power Felt. Innovation charging other mobiles can also be done with cycling, with water and power at the end of May 2013 found that mobile phone battery charger only takes 20 seconds.
